Abstract (en)

[origin: EP3591874A1] A data transmission method and apparatus in a time division duplex system is disclosed, where the method includes: receiving, by a terminal device in a downlink control part, first downlink control information and a first downlink reference signal that are sent by a network device; receiving, by the terminal device in a first downlink data part according to the first downlink control information, first data sent by the network device; generating, by the terminal device, feedback information based on the first downlink reference signal and the first data; sending, by the terminal device, the feedback information to the network device in an uplink feedback part; and receiving, by the terminal device in a second downlink data part according to the first downlink control information, second data sent by the network device; where the downlink control part, the first downlink data part, the uplink feedback part, and the second downlink data part constitute a first time unit. With the present invention, a transmission latency can be reduced in a communications system.
